Two centuries ago, a British geologist gave the world its first named dinosaur. Megalosaurus, described from a handful of fossilised bones, marked the birth of an entire scientific field.

Around 1200 BCE, several of the eastern Mediterranean's most powerful civilisations, including the Mycenaean kingdoms, the Hittite Empire, Canaanite city-states and parts of New Kingdom Egypt, began experiencing a period of dramatic decline. Historians have long debated whether warfare, invasions, earthquakes, internal unrest or climate change played the biggest role in this Bronze Age collapse.

In 1976, ornithologist George Archibald began an unusual daily ritual, dancing beside a whooping crane named Tex in an attempt to save one of the rarest birds on the planet. Tex had been raised in captivity and had imprinted on humans rather than other cranes, meaning she showed no interest in mating with her own species.

Concrete is the backbone of modern civilisation, supporting everything from homes and skyscrapers to bridges, tunnels and dams. Yet even this remarkably strong material has a costly weakness.

Scientists studying ants have found that the brain circuits that caregiving behaviour may have evolved from far older circuits that originally controlled hunger. The research, carried out on clonal raider ants at Rockefeller University and published in the journal Nature, shows that two chemical signals in the ant brain, known as neuropeptide F and allatostatin A, control whether an individual ant acts as a caregiver to larvae or leaves the nest to forage for food.

A proof-of-concept study combined AI with a photonic quantum computer to design immune peptides. Corresponding author Timothy Patrick Jenkins told The Indian Express how the technology could advance personalised cancer vaccines.

Scientists say a strengthening super El Nino is loading the atmosphere with heat and may delay the peak impact until 2027. That lag, combined with greenhouse-driven warming, could intensify extreme weather and push global temperatures to a new record.

Bats rely on echolocation to move through the dark and hunt insects. They send out high-pitched sound waves that bounce off nearby objects and return as echoes which helps them judge where things are.

Birds may sound different depending, but scientists have now found that many of their songs are built from the same basic set of sound patterns. A new global study has identified eight recurring motifs that appear in the songs of thousands of bird species.

For years, scientists have believed one major reason insects are almost absent from the ocean is simple physics: their air-filled bodies would collapse under deep-water pressure. But a tiny insect larva living in Africa's Lake Malawi is challenging that idea in a surprising way.
